+
+Returns the current WLED configuration including host and all segments.
+
+- **URL:** `/api/wled/config`
+- **Method:** `GET`
+- **Response:**
+
+```json
+{
+  "host": "192.168.1.100",
+  "segments": [
+    {
+      "name": "Main Light",
+      "start": 0,
+      "leds": 60
+    },
+    {
+      "name": "Accent Light",
+      "start": 60,
+      "leds": 30
+    }

+| host               | string | Yes      | WLED host address (IP or hostname)       |
+| segments           | array  | Yes      | List of LED segments (can be empty)      |
+| segments[].name    | string | No       | Optional segment name                    |
+| segments[].start   | number | Yes      | Start LED index (0-based)                |

+- **Response:** `200 OK` on success, `400 Bad Request` on validation error
+
+**Notes:**
+- The firmware uses this configuration to communicate with a WLED controller
+- Segments are mapped to the WLED JSON API segment control
+- Changes are persisted to NVS (non-volatile storage)
+- The host can be an IP address (e.g., `192.168.1.100`) or hostname (e.g., `wled.local`)
